The objective of the NIH Career Transition Award (K22) is to provide support to outstanding basic or clinical investigators to develop their independent research skills through a two phase program: an initial period involving an intramural appointment at the NIH and a final period of support at an extramural institution. This NINDS K22 is specifically designed to facilitate the transition of NINDS intramural neurologist- and neurosurgeon-scientists to independent, academic faculty positions that support clinician-scientists to engage in independently funded scientific research as well as clinical activities.

Understanding the dynamic activity of neural circuits is central to the NIH BRAIN Initiative. This FOA seeks applications for proof-of-concept testing and development of new technologies and novel approaches for largescale recording and manipulation of neural activity to enable transformative understanding of dynamic signaling in the nervous system. In particular, we seek exceptionally creative approaches to address major challenges associated with recording and manipulating neural activity, at or near cellular resolution, at multiple spatial and/or temporal scales, in any region and throughout the entire depth of the brain. It is expected that the proposed research may be high-risk, but if successful could profoundly change the course of neuroscience research. Proposed technologies should be compatible with experiments in behaving animals, and should include advancements that enable or reduce major barriers to hypothesis-driven experiments. Technologies may engage diverse types of signaling beyond neuronal electrical activity for large-scale analysis, and may utilize any modality such as optical, electrical, magnetic, acoustic or genetic recording/manipulation. Applications that seek to integrate multiple approaches are encouraged. Where appropriate, applications are expected to integrate appropriate domains of expertise, including biological, chemical and physical sciences, engineering, computational modeling and statistical analysis.

The purpose of the administrative supplement is to provide support for NIH-funded investigators to participate in an entrepreneurship training course, the Concept to Clinic: Commercializing Innovation (C3i) Program. The C3i Program is designed to provide medical device innovators with the specialized business frameworks and essential tools for successful translation of biomedical technologies from the lab (concept) to the market (clinic). Through this program, the NIH fosters the development and commercialization of early-stage biomedical technologies by engaging investigators who are interested in better understanding the value of their innovation in addressing an unmet market need. The curriculum and customized mentoring provided by the C3i Program are intended to guide investigators as they assess the commercial viability and potential business opportunity for their innovation. Prospective applicants are strongly encouraged to contact NIH Scientific/Research staff for more information about the program before applying.

A central goal of the BRAIN Initiative is to understand how electrical and chemical signals code information in neural circuits and give rise to sensations, thoughts, emotions and actions. While currently available technologies can provide some understanding, they may not be sufficient to accomplish this goal. For example, non-invasive technologies are low resolution and/or provide indirect measures such as blood flow, which are imprecise; invasive technologies can provide information at the level of single neurons producing the fundamental biophysical signals, but they can only be applied to tens or hundreds of neurons, out of a total number in the human brain estimated at 85 billion. Other BRAIN FOAs seek to develop novel technology (RFA-NS-17-003) or to optimize existing technology ready for in-vivo proof-of-concept testing and collection of preliminary data (RFA-NS-17-004) for recording or manipulating neural activity on a scale that is beyond what is currently possible. This FOA seeks applications for unique and innovative technologies that are in an even earlier stage of development than that sought in other FOAs, including new and untested ideas that are in the initial stages of conceptualization. In addition to experimental approaches, the support provided under this FOA might enable calculations, simulations, computational models, or other mathematical techniques for demonstrating that the signal sources and/or measurement technologies are theoretically capable of meeting the demands of large-scale recording or manipulation of circuit activity in humans or in animal models. The support might also be used for building and testing phantoms, prototypes, in-vitro or other bench-top models in order to validate underlying theoretical assumptions in preparation for future FOAs aimed at testing in animal models.
